// considered to have drifted if one or more of its resources differ from their
// expected template configurations. For more information, see Detecting Unregulated
// Configuration Changes to Stacks and Resources (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-stack-drift.html).

	//    * CAPABILITY_AUTO_EXPAND Some template contain macros. Macros perform
	//    custom processing on templates; this can include simple actions like find-and-replace
	//    operations, all the way to extensive transformations of entire templates.
	//    Because of this, users typically create a change set from the processed
	//    template, so that they can review the changes resulting from the macros
	//    before actually creating the stack. If your stack template contains one
	//    or more macros, and you choose to create a stack directly from the processed
	//    template, without first reviewing the resulting changes in a change set,
	//    you must acknowledge this capability. This includes the AWS::Include (http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/create-reusable-transform-function-snippets-and-add-to-your-template-with-aws-include-transform.html)

	//    contains macros and nested stacks, you must create or update the stack

	//    Because of this, users typically create a change set from the processed

	//    transforms, which are macros hosted by AWS CloudFormation. Change sets
	//    do not currently support nested stacks. If you want to update a stack
	//    from a stack template that contains macros and nested stacks, you must
	//    update the stack directly from the template using this capability. You
	//    should only update stacks directly from a stack template that contains
	//    macros if you know what processing the macro performs. Each macro relies
